    Oil hot water boiler size

    I think I understand net ratings. I usually do not think about them. I typically work with commercial systems which have pipe insulation. For that matter usually two slightly over sized boilers are used.
    I am looking at a new single family residence with radiant heat which needs an oil fired boiler. The house load is about 115MBH. Should I size that boiler based on the gross output or should I count on some losses?
